Question 1139393
if the price of the jacket is 90 dollars today and inflation is 2% per year, then the price of the jacket in 10 years will be 1.02 ^ 10 * 90 = 109.7094978 dollars.


your 90 dollars buys 100% of the price of the jacket today.


your same 90 dollars can only buy 90 / 109.7094978 = .8203482999 * 100 = 82.03482999% of the price of the jacket 10 years from now.


that's a drop in buying power from 100% to 82.03482999% = 17.96517001%.
